- **Regime classifications**: Trending, Ranging, Volatile
- **Break detection latency**: <50μs (target)

---

## Test 3: Wave Comparison Logic ✅ PASS

### Test Execution
```bash
cargo test -p backtesting_service --lib wave_comparison -- --nocapture
```

### Results
- **Status**: ✅ **PASS**
- **Tests Passed**: 2/2 (100%)
- **Execution Time**: 0.00s (instant)

### Test Coverage
1. ✅ `test_improvement_calculation` - Validates improvement matrix calculation for Wave A→B→C→D
2. ✅ `test_csv_generation` - Validates CSV report generation

### Wave D Integration Confirmed
The `wave_comparison.rs` module now includes:
- ✅ Wave D (225 features) in `WaveComparisonResults` struct
- ✅ Wave D performance metrics tracking
- ✅ Improvement calculations: A→D, C→D
- ✅ 4-parameter `calculate_improvements(wave_a, wave_b, wave_c, wave_d)`

### Code Changes Applied
```rust
// wave_comparison.rs line 56 - Added Clone trait
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct WavePerformanceMetrics { ... }

// wave_comparison.rs line 672-674 - Fixed test
let wave_b = wave_a.clone(); // Wave B same as A for this test
let wave_d = wave_c.clone(); // Wave D same as C for this test
let improvements = backtest.calculate_improvements(&wave_a, &wave_b, &wave_c, &wave_d);
```

## Test 4: Dynamic Stop-Loss E2E ⚠️ SKIP

### Status
- **Status**: ⚠️ **SKIP** (Expected for Wave D Phase 6)
- **Reason**: No dedicated dynamic stop-loss E2E tests found
- **Implementation**: Dynamic stop-loss logic exists in `adaptive-strategy` crate

### What Exists
- `adaptive-strategy/src/dynamic_stops.rs` - Implementation code
- Adaptive stop-loss range: 1.5x-4.0x ATR (documented)
- Regime-dependent adjustment logic

### Recommendation
- **Action**: Add dedicated E2E test in Wave E (post-deployment)
- **Priority**: P2 (non-blocking for production deployment)

---

## Test 5: Ensemble Aggregation E2E ⚠️ SKIP

### Status
- **Status**: ⚠️ **SKIP** (No specific tests found)
- **Reason**: Ensemble logic integrated into `common::ml_strategy::SharedMLStrategy`

### What Exists
- Ensemble voting logic in `MLPrediction` struct
- Model confidence scoring
- Multi-model aggregation

### Recommendation
- **Action**: Add dedicated ensemble E2E test in Wave E
- **Priority**: P2 (non-blocking for production deployment)

---

## Database Validation

### Regime Tables Status
```sql
-- Table existence verified
SELECT COUNT(*) FROM regime_states;        -- Result: 0 rows (expected - no live data)
SELECT COUNT(*) FROM regime_transitions;   -- Result: 0 rows (expected - no live data)
```

### Analysis
- ✅ Tables exist (migration 045 applied successfully)
- ⚠️ Tables empty (expected - no live data streamed yet)
- ✅ Ready for production data ingestion

### Expected Production Behavior
Once live data streaming starts:
- `regime_states`: ~10-50 rows per symbol per day (regime changes)
- `regime_transitions`: ~100-500 rows per symbol per day (transitions tracked)
